- Ceramics When the temperature of a pot in a kiln is 1200, an artist turns off the heat and leaves the pot to cool at a controlled rate of 18 per hour. Express the temperature of the pot in degrees Celsius as a function of the time t in hours since the kiln was turned off.arrow_forwardTable 6 shows the year and the number ofpeople unemployed in a particular city for several years. Determine whether the trend appears linear. If so, and assuming the trend continues, in what year will the number of unemployed reach 5 people?arrow_forwardA Ferris wheel loads passengers at a height 2 meters above the ground and carries them to height atmost 16 meters above the ground. It takes 4 minutes for the wheel to rotate once fully. Draw the graph of anapproximate function which models the height of a passenger on the Ferris wheel with respect to time wherethe passenger starts at the lowest point on the Ferris wheel. Make sure to include two periods.arrow_forward
- Plot the Function x+earrow_forwardA person invested $530 in an account growing at a rate allowing the money to double every 8 years. Write a function showing the amount of money in the account after t years, where the annual growth rate can be found from a constant in the function. Round all coefficients in the function to four decimal places. Also, determine the percentage of growth per year, to the nearest hundredth of a percentarrow_forwardy = 3 csc(x) Graph the function.arrow_forward
